GS Renovation designs and builds extensions throughout Tottenham, working with the bay-fronted Victorian and Edwardian terraces that fill the N17 streets around Wood Green and towards Finsbury Park. With more than 30 years in North London, we handle groundworks, steel, roofing and full fit-out, and guide you through Haringey planning where it applies.
Side-return and rear extensions in Tottenham
The most requested project on a Tottenham terrace is the side-return infill, filling the narrow alley beside the rear closet wing to widen a cramped galley kitchen into a proper kitchen-diner. We dig and pour new foundations to building regulations depth, tie into the existing brickwork, and install a steel beam where the old external wall is removed, all signed off by building control.
Rear extensions off these Victorian and Edwardian homes work well too, and can be combined with the side return as a wrap-around. We match the stock brick and detailing so the addition sits comfortably against the period elevation, and set roof lights or a lantern over the deeper plan to keep the middle of the house bright, which matters on these long, narrow N17 plots.
Planning and party walls in Haringey
Whether your Tottenham extension is permitted development or needs a full application to Haringey Council depends on the property. Many single storey rear extensions fall under permitted development rights, but corner plots, previous additions, an Article 4 direction or a conservation setting can remove those rights and require planning permission. We assess your specific house first and, where needed, prepare and submit the application for you.
Double storey and wrap-around schemes almost always need a planning application, and any extension still has to meet building regulations for structure, insulation, drainage and fire safety regardless of planning. Because the flank and rear walls of these terraces are shared, most extensions also trigger the Party Wall Act, so we serve notices to the neighbours either side and agree the position before the diggers arrive.
